About Boomstone

Boomstone is a color-matching puzzle game where you blast veins of gems to rack up massive scores. Eight gems appear on the wall, each showing a color and a purity value. Your job is to arrange matching colors into connected lines—called veins—then detonate them for points. The higher the combined purity, the bigger your score multiplier, letting you climb from double digits into the tens of thousands. You'll work your way down through eight increasingly challenging mine layers. Between layers you visit a supply station to pick upgrades: boost a specific color's value, double the points from matching blasts, or power up your last move of the layer. The upgrades shuffle every playthrough, so each run on Poki Games feels different. Watch out for boss anomalies at the end of each layer—they might lock a color or remove one of your moves, forcing you to rethink your strategy on the fly.
